Monitor Description

WARNING: This page is about a different variant/trim than selected.

The NT terminal of the ECM detects a revolution signal from the speed sensor (NT) (input RPM). The ECM calculates gear shifts comparing the speed sensor (NT) with the speed sensor (NC).

While the vehicle is being driven in 2nd, 3rd, 4th or 5th gear with the shift lever in D, if the input shaft revolution (speed) is less than 300 rpm*1 and the output shaft revolution (speed) is more than 1000 rpm*2, the ECM interprets this as a fault, illuminates the MIL and stores a DTC.

*1: Pulse is not output or is irregularly output.

*2: The vehicle speed is 50 km/h (31 mph) or more.
